Return Dispersion as an Estimator of Learning Potential for Prioritized Level Replay

no code implementations NeurIPS Workshop ICBINB 2021 Iryna Korshunova, Minqi Jiang, Jack Parker-Holder, Tim Rocktäschel, Edward Grefenstette

Prioritized Level Replay (PLR) has been shown to induce adaptive curricula that improve the sample-efficiency and generalization of reinforcement learning policies in environments featuring multiple tasks or levels.

Discriminative Topic Modeling with Logistic LDA

1 code implementation NeurIPS 2019 Iryna Korshunova, Hanchen Xiong, Mateusz Fedoryszak, Lucas Theis

We propose logistic LDA, a novel discriminative variant of latent Dirichlet allocation which is easy to apply to arbitrary inputs.

BRUNO: A Deep Recurrent Model for Exchangeable Data

3 code implementations NeurIPS 2018 Iryna Korshunova, Jonas Degrave, Ferenc Huszár, Yarin Gal, Arthur Gretton, Joni Dambre

We present a novel model architecture which leverages deep learning tools to perform exact Bayesian inference on sets of high dimensional, complex observations.

Faster gaze prediction with dense networks and Fisher pruning

2 code implementations Twitter 2018 Lucas Theis, Iryna Korshunova, Alykhan Tejani, Ferenc Huszár

Predicting human fixations from images has recently seen large improvements by leveraging deep representations which were pretrained for object recognition.

Fast Face-swap Using Convolutional Neural Networks

no code implementations ICCV 2017 Iryna Korshunova, Wenzhe Shi, Joni Dambre, Lucas Theis

We consider the problem of face swapping in images, where an input identity is transformed into a target identity while preserving pose, facial expression, and lighting.

Music transcription modelling and composition using deep learning

2 code implementations29 Apr 2016 Bob L. Sturm, João Felipe Santos, Oded Ben-Tal, Iryna Korshunova

We apply deep learning methods, specifically long short-term memory (LSTM) networks, to music transcription modelling and composition.
